Within Wikipedia, notability is an inclusion criterion based on the encyclopedic suitability of an article topic. The topic of an article should be notable, or "worthy of notice"; that is, "significant, interesting, or unusual enough to deserve attention or to be recorded".[୧]Notable in the sense of being "famous", or "popular"—although not irrelevant—is secondary.

If the depth of coverage in any given source is not substantial, then multiple independent sources may be combined to demonstrate notability; trivial coverage of a subject by secondary sources may not be sufficient to establish notability.[୬]

Primary sources may be used to support content in an article, but they do not contribute toward proving the notability of a subject.

People are likely to be notable if they meet any of the following standards. Failure to meet these criteria is not conclusive proof that a subject should not be included; conversely, meeting one or more does not guarantee that a subject should be included.

A person who fails to meet these additional criteria may still be notable under Wikipedia:Notability.

Many scientists, researchers, philosophers and other scholars (collectively referred to as "academics" for convenience) are notably influential in the world of ideas without their biographies being the subject of secondary sources.

The person is regarded as an important figure or is widely cited by peers or successors.

The person is known for originating a significant new concept, theory or technique.

The person has created, or played a major role in co-creating, a significant or well-known work, or collective body of work, that has been the subject of an independent book or feature-length film, or of multiple independent periodical articles or reviews.

The person's work either (a) has become a significant monument, (b) has been a substantial part of a significant exhibition, (c) has won significant critical attention, or (d) is represented within the permanent collections of several notable galleries or museums.

A person who is notable only for being the victim of or committing a crime or crimes should not normally be the subject of a separate Wikipedia article if there are any existing articles that do or could incorporate the available encyclopaedic material relating to that person.

Where there is such an existing article, it may be appropriate to create a sub-article, but only if this is necessitated by considerations of article size.

Where there are no appropriate existing articles, the criminal or victim in question should be the subject of a Wikipedia article only if one of the following applies:

For victims

The victim, consistent with WP:BLP1E, had a large role within a well-documented historic event. The historic significance is indicated by persistent coverage of the event in reliable secondary sources that devote significant attention to the individual's role.[୮]

The motivation for the crime or the execution of the crime is unusual—or has otherwise been considered noteworthy—such that it is a well-documented historic event. Generally, historic significance is indicated by sustained coverage of the event in reliable secondary sources which persists beyond contemporaneous news coverage and devotes significant attention to the individual's role.[୧୦]

Note: A living person accused of a crime is not guilty unless and until this is decided by a court of law. Editors must give serious consideration to not creating an article on an alleged perpetrator when no conviction is yet secured.

Diplomats who have participated in a significant way in events of particular diplomatic importance that have been written about in reliable secondary sources. Sufficient reliable documentation of their particular role is required.

Has made unique contributions to a specific pornographic genre, such as beginning a trend in pornography; starred in an iconic, groundbreaking or blockbuster feature; or is a member of an industry Hall of Fame such as the AVN Hall of Fame, XRCO Hall of Fame or equivalent.

Politicians and judges who have held international, national or sub-national (statewide/provincewide) office, and members or former members of a national, state or provincial legislature.[୧୨] This will also apply to those who have been elected but not yet sworn into such offices.

Major local political figures who have received significant press coverage.[୭]

Just being an elected local official, or an unelected candidate for political office, does not guarantee notability, although such people can still be notable if they meet the primary notability criterion of "significant coverage in reliable sources that are independent of the subject of the article".

In the case of candidates for political office who do not meet this guideline, the general rule is to redirect to an appropriate page covering the election or political office sought in lieu of deletion. Relevant material from the biographical article can be merged into the election or political office page if appropriate.[୧୩]

Avoid criteria based on search engine statistics (e.g., Google hits or Alexa ranking), or measuring the number of photos published online. The adult film industry, for example, uses Googlebombing to influence rankings, and for most topics search engines cannot easily differentiate between useful references and mere text matches. See also limitations of Alexa. When using a search engine to help establish the notability of a topic, evaluate the quality, not the quantity, of the links.

If no criteria can be met for either a standalone article or inclusion in a more general article, and improvements have not worked or cannot be reasonably tried, then there are three deletion procedures to be considered:[୧୪]

Put the {{notability|biographies}} tag on the article to notify other editors.

If the article is about a specialized field, use the {{expert-subject}} tag with a specific WikiProject to attract editors knowledgeable about that field, who may have access to reliable sources not available online.

When an individual is significant for his or her role in a single event, it may be unclear whether an article should be written about the individual, the event or both. In considering whether or not to create separate articles, the degree of significance of the event itself and the degree of significance of the individual's role within it should be considered. The general rule in many cases is to cover the event, not the person. However, as both the event and the individual's role grow larger, separate articles become justified.[୧୬]

If the event is highly significant, and the individual's role within it is a large one, a separate article is generally appropriate. The assassins of major political leaders, such as Gavrilo Princip, fit into this category, as indicated by the large coverage of the event in reliable sources that devotes significant attention to the individual's role.

When the role played by an individual in the event is less significant, an independent article may not be needed, and a redirect is appropriate. For example, George Holliday, who videotaped the Rodney King beating, redirects to Rodney King. On the other hand, if an event is of sufficient importance, even relatively minor participants may require their own articles, for example Howard Brennan, a witness to the JFK assassination.

Another issue arises when an individual plays a major role in a minor event. In this case, it is not generally appropriate to have an article on both the person and the event. Generally in this case, the name of the person should redirect to the article on the incident, especially if the individual is only notable for that incident and is all that that person is associated with in source coverage. For example, Steve Bartman redirects to Steve Bartman incident. In some cases, however, a person famous for only one event may be more widely known than the event itself, for example, the Tank Man. In such cases, the article about the event may be most appropriately named for the person involved.

Many articles contain (or stand alone as) lists of people. Inclusion within stand-alone lists should be determined by the notability criteria above. Inclusion in lists contained within articles should be determined by WP:Source list, in that the entries must have the same importance to the subject as would be required for the entry to be included in the text of the article according to Wikipedia policies and guidelines (including WP:Trivia sections). Furthermore, every entry in any such list requires a reliable source attesting to the fact that the named person is a member of the listed group.

For instance, articles about schools often include (or link to) a list of notable alumni, but such lists are not intended to contain every graduate of the school—only those with verifiable notability. Editors who would like to be identified as an alumnus/alumna should instead use the categories intended for this purpose, e.g. Category:Wikipedians by alma mater. On the other hand, a list within an article of past school presidents can contain all past presidents, not just those who are independently notable.

↑Sources that are pure derivatives of an original source can be used as references, but do not contribute toward establishing the notability of a subject. "Intellectual independence" requires not only that the content of sources be non-identical, but also that the entirety of content in a published work not be derived from (or based in) another work (partial derivations are acceptable). For example, a speech by a politician about a particular person contributes toward establishing the notability of that person, but multiple reproductions of the transcript of that speech by different news outlets do not. A biography written about a person contributes toward establishing his or her notability, but a summary of that biography lacking an original intellectual contribution does not.

↑Autobiography and self-promotion are not the routes to having an encyclopaedia article. The barometer of notability is whether people independent of the subject itself have actually considered the subject notable enough that they have written and published non-trivial works that focus upon it. Thus, entries in biographical dictionaries that accept self-nominations (such as the Marquis Who's Who) do not prove notability.

↑Non-triviality is a measure of the depth of content of a published work, and how far removed that content is from a simple directory entry or a mention in passing ("John Smith at Big Company said..." or "Mary Jones was hired by My University") that does not discuss the subject in detail. A credible 200-page independent biography of a person that covers that person's life in detail is non-trivial, whereas a birth certificate or a 1-line listing on an election ballot form is not. Database sources such as Notable Names Database, Internet Movie Database and Internet Adult Film Database are not considered credible since they are, like wikis, mass-edited with little oversight. Additionally, these databases have low, wide-sweeping generic standards of inclusion.

↑ ୭.୦୭.୧Generally, a person who is "part of the enduring historical record" will have been written about, in depth, independently in multiple history books on that field, by historians. A politician who has received "significant press coverage" has been written about, in depth, independently in multiple news feature articles, by journalists. An actor who has been featured in magazines has been written about, in depth, independently in multiple magazine feature articles, by magazine article writers. An actor or TV personality who has "an independent biography" has been written about, in depth, in a book, by an independent biographer.

↑This is a secondary criterion. People who satisfy this criterion will almost always satisfy the primary criterion. Biographers and historians will usually have already written about the past and present holders of major political offices. However, this criterion ensures that our coverage of major political offices, incorporating all of the present and past holders of that office, will be complete regardless.

↑Deleting a biography in these cases instead of merely redirecting it makes recovering useful information from the page history difficult, and should be done only when there are relevant reasons other than lack of notability for removing the article from the mainspace.

↑Wikipedia editors have been known to reject nominations for deletion that have been inadequately researched. Research should include attempts to find sources which might demonstrate notability, and/or information which would demonstrate notability in another manner.

↑The text of an article should include enough information to explain why the person is notable. External arguments via a talk page or AFD debate page are not part of the article itself, and promises on those pages to provide information are not as valid as the existence of the information on the article page itself.

↑It is important for editors to understand two clear differentiations of WP:BIO1E when compared to WP:BLP1E. Firstly, WP:BLP1E should be applied only to biographies of living people. Secondly, WP:BLP1E should be applied only to biographies of low profile individuals.
